Abstract: A circuit for providing current to a laser tube permits high current, high output voltage, and high frequency modulation response (e.g., up to about 1 MHz, in one embodiment) with low power dissipation. This is accomplished by combining the output current from two current sources, one of which is a high amplitude low frequency current mode switched mode power supply, while the other current source is a low amplitude, high frequency current source.

Abstract: In the manufacture of a substrate with a hydrophobic film used for a reference electrode of an ion sensor or the like, a hydrophobic film is formed on a substrate (6) by irradiating a target (5) consisting of a hydrophobic compound with a neutral atom beam and thereby effecting spattering. The apparatus for effecting the spattering comprises a target base (12) disposed in a vacuum chamber, an atom beam gun (11) for irradiating a target on the target base with a neutral beam, a substrate base (13) and a shutter (14) for controlling the passage of spattered particles. A thin film that is manufactured is suitable for an ion sensor,such as an ISFET or the like or an enzyme sensor.

Abstract: Accumulator injector comprising a needle valve (30), an accumulator chamber and an amplifier chamber (64) in communication with the source of pressurized fuel, the end (74) of the valve (30) being subjected to the pressure in the amplifier chamber (64). An amplifier piston (70') is provided for boosting the pressure in in the amplifier chamber (64) and in the accumulator chamber. A duct (80') extends from a valve assembly (82) along side of and spaced from the amplifier cylinder (72) and communicates with the cylinder (72) by means of a smaller lower port (106) and a larger upper port (108). By restricting the rate of movement of the amplifier piston (70') upwardly, the pressure in the amplifier chamber (64) and hence in the accumulator chamber is relieved at a slower rate, hence changing the rate of opening of the needle valve (30) and the rate of fuel injection. The initial fuel flow from the end chamber (116) through the small port (106) produces a pilot injection. The injection rate is controlled by restricting the pressure decay in the amplifier chamber (64).

Abstract: A set of "m" feature parameters is generated every frame from reference speech which is spoken by at least one speaker and which represents recognition-object words, where "m" denotes a preset integer. A set of "n" types of standard patterns is previously generated on the basis of speech data of a plurality of speakers, where "n" denotes a preset integer. Matching between the feature parameters of the reference speech and each of the standard patterns is executed to generate a vector of "n" reference similarities between the feature parameters of the reference speech and each of the standard patterns every frame. The reference similarity vectors of respective frames are arranged into temporal sequences corresponding to the recognition-object words respectively. The reference similarity vector sequences are previously registered as dictionary similarity vector sequences. Input speech to be recognized is analyzed to generate "m" feature parameters from the input speech. Matching between the feature parameters of the input speech and the standard patterns is executed to generate a vector of "n" input-speech similarities between the feature parameters of the input speech and the standard patterns every frame. The input-speech similarity vectors of respective frames are arranged into a temporal sequence. The input-speech similarity vector sequence is collated with the dictionary similarity vector sequences to recognize the input speech.

Abstract: The performance of a hysteresis address input buffer of a VLSI ROM is improved by providing additional driving power to establish the high and low voltage transition points of the input buffer. The address transition detection circuit is improved by holding the previously latched address signal until a predetermined delay after receipt of the new address signal. The operation of signal buffers can be stabilized and the emission electrons avoided by selectively coupling the input to the last stage of the buffer to a predetermined voltage during any precharge hold time interval. The memory array is improved by providing an architecture for the columns of memory cells so that the signal from the address memory cell need propagate only on the diffusion bit lines by a distance no greater and no less than the length of the diffusion bit line within a single block of the memory cells. The architecture of the memory layout is improved by providing bit line and virtual ground line contacts at opposing ends of the memory block and by replicating the memory block through mirror symmetry on the semiconductor substrate.

Abstract: Methanol is produced from synthesis gas comprising hydrogen, carbon monoxide, and carbon dioxide in a two-stage liquid phase reactor system. Each reactor is operated in an optimum temperature range to maximize methanol productivity, and once-through product conversion of up to 9.1 moles methanol per 100 moles of synthesis gas can be achieved with reasonable catalyst utilization. Overall catalyst utilization is increased by countercurrent catalyst transfer. In an alternate mode of operation, the liquid phase reactor system is integrated with a coal gasification combined cycle (CGCC) power generation process wherein the unreacted synthesis gas is used as fuel in a gas turbine-driven electric power generator. Operation of each liquid phase reactor in the optimum temperature range maximizes the available heat of reaction which is recovered as steam; the steam is utilized in the gas turbine combustor or the CGCC steam turbine. Methanol from the liquid phase reactor system can be used as peak shaving fuel for the gas turbine.

Abstract: An actuator for a multiple-position electrical switch includes an actuator member (22) having a cam surface formed on its undersurface along each edge. Two pairs of cam followers (80,82,84,86) formed at the end of respective resilient beams (70,72,74,76) slide along the cam surface. The cam surface is formed with a series of ridges and indentations corresponding to the actuator switch positions. Thus, the actuator member can be moved between adjacent switch positions only by exerting sufficient force to lift each of the cam followers over a ridge from one indentation to the adjacent indentation. An additional cam follower (92) is resiliently biased against an additional cam surface formed on the underside of the actuator member when the actuator member is moved to one switch position. As a result, the force required to move the actuator member to one switch position is greater than the force required to move the actuator member between other switch positions.
